INTRODUCTION

Many devices now use electronic graphical user interfaces (GUIs) as theprimary user interface means instead of panels with mechanical elementssuch as knobs, buttons, switches etc. These GUIs are typically presentedon a suitably-sized display (such as a flat panel display) inconjunction with a pointing or, as is increasingly common, atouch-sensitive display.

A drawback of electronic GUIs is the power consumption the displaysrequire. Large and high resolution displays and support circuitry oftenconsume excessive amounts of power, making them unattractive for usewith battery-powered devices.

Yet another drawback related to the power consumption issue is that inorder for an operator to interact with or obtain information from thedevice in any way, the electronic GUI must be powered on, even when theinformation needed is unrelated to the operation of the device. Forexample, a device may have a battery that can be charged from wall powerwhen the device is turned off. If the electronic GUI is the onlyinterface, then in order to simply determine the charge condition of thebattery, the device must be turned on in order to power the electronicGUI. Further, if the electronic GUI is the only interface, then anoperator must turn on the device when selecting a ventilator for use onpatient, to determine the ventilator configuration, ventilationprograms, ventilator identification information, and maintenanceinformation.

One way that has been used to address this problem is to providecombinations of limited function alpha numeric displays, lamps and LEDsin addition to the primary display to manage ancillary or statusinformation that should be provided to the operator. However, suchancillary user interface elements can not be reconfigured as they arebuilt into their devices. Therefore, if different operators want to seedifferent types of ancillary information, the only way to achieve thisis to create different physical housings for each set of ancillaryinformation desired by consumers.

Another drawback to currently utilized ventilator systems is thatdifferent ventilators are often configured differently, making itdifficult for ventilator operators to quickly find and/or locate thephysical components of the ventilator. During ventilation, the operatorneeds to understand the status of the ventilator in addition to thestatus of the patient to properly care for the patient. Current systemsprovide stickers or papers on the ventilator system to direct theoperator to proper parts in an attempt to help alleviate this problem;however, these stickers and papers may fade or fall off the ventilatorover time.

An additional drawback to currently utilized ventilator systems is thatthe increased specificity and wide variety of ventilator systems andprograms makes it difficult for a ventilator operator to quickly choosea desired and/or proper ventilator. The ventilator operator may have alimited amount of time to determine if a ventilator provides the neededfeatures, contains enough of the desired gas source, and/or is properlyconfigured, charged, maintained, and/or serviced. Because ventilatorsare typically utilized in complicated environments, such as in intensivecare units, the operator may have a limited amount of time to pick andcompletely understand a ventilator. The large number of differencesbetween different ventilators increases the amount of time necessary foran operator to pick and completely understand a ventilator, which is anundesirable side-effect of ventilator variety and specialization.

DETAILED DESCRIPTION

This disclosure describes embodiments of novel display methods and of asystem status display for use in devices such as medical ventilatorsthat have an electronic graphical user interface (GUI) on a primarydisplay device. The system status display (SSD) is a secondary displaythat has a more limited functionality than the electronic GUI on theprimary display, and is provided primarily, if not solely, for thepurpose of providing system status information to the operator.

Although the technology introduced above and discussed in detail belowmay be implemented for a variety of devices (and not just medicaldevices), the present disclosure will discuss the implementation ofthese techniques in the context of a medical ventilator for use inproviding ventilation support to a human patient. The reader willunderstand that the technology described in the context of a medicalventilator for human patients could be adapted for use with othersystems such as ventilators for non-human patients, different types ofmedical devices and any devices that use an electronic GUI presented ona primary display.

Medical ventilators are used to provide mixed gases that can bedelivered in different modes of operation to a patient who may otherwisebe unable to breathe sufficiently. This could include assisting a weaklybreathing patient by reducing the work of breathing or by breathing fora patient that is unable to breathe. In modern medical facilities,pressurized air and oxygen sources are often available from walloutlets. Other, exotic gases such as helium, helium-oxygen mixtures(heliox), nitrogen and argon to name but a few, may also be useddepending on the therapy being administered.

Medical ventilators monitor the delivery of breathing gas to thepatient, may directly or indirectly monitor physiological parameters ofthe patient, and monitor the operation of the ventilator.

In the embodiments described herein, operators control the medicalinterface through an electronic GUI presented on a primary display,possibly in conjunction with one or more user input devices such as athumbwheel, mouse, keyboard, or selector. As described above, typically,such a primary display is a large display which may be provided withtouchscreen capability. The electronic GUI presented to the operator viathis display allows the operator to view patient data in differentforms, historical data, control the operation of the ventilator andchange the therapy being provided to the patient. In an embodiment,every ventilator operation that can be performed by the ventilator canbe accessed via the electronic GUI. Further, the electric GUI may or maynot be removable from the ventilator housing.

Because of the computing power necessary to drive such a primarydisplay, a separate GUI controller (which may alternatively be referredto as the primary display controller or graphics subsystem) is oftenused that is solely dedicated to running the primary display,interpreting user inputs received through the GUI, and passing thatinformation on to the main ventilator controller that controls theactual gas delivery operations of the ventilator and any subsystemswithin the ventilator. Another function is to perform the computationsand manipulations necessary to raw data provided by the main ventilatorcontroller or discreet ventilator subsystems and turn them into thegraphical presentations (waveforms, loops, monitored patient data,average values, etc.) shown on the GUI. For example, in an embodiment,the main ventilator controller monitors and outputs current parameters,which are then stored in memory to be accessed as needed by the GUIcontroller.

An example of one such subsystem is a battery control system. Typically,medical ventilators may be provided with one or more batteries to allowthe ventilator to remain in operation without interruption while apatient is being transported between locations or during power loss. Thebattery system may include a monitoring and recharging subsystem thatmonitors the charge state and performance of the battery or batteriesand keeps the batteries in a charged state.

Depending on the configuration of the ventilator other subsystems may beprovided such as modules associated with gas sources, e.g., which gassources are currently in use or modules associated with power managementsuch as whether power is being delivered from a wall outlet or thebattery system,

The SSD of the present disclosure is a secondary display that provideslimited status information to the operator. In an embodiment, the SSDmay not be interactive in any way, rather only providing statusinformation in a predetermined or preselected format. Alternatively,some limited interaction may be provided through which a limited set ofcommands may be provided directly to the main breath deliverycontroller.

The SSD may be completely independent of the primary display and the GUIcontroller. One benefit of this architecture is that it allows theprimary display and, thus the GUI, to be powered down or even completelyremoved from the ventilator while continuing to provide the operatorwith status of gas delivery to the patient and system statusinformation. In another embodiment, the SSD is completely independent ofthe ventilation system. One benefit of this architecture is that itallows the ventilator to be powered down while continuing to provide theoperator with system status information on the SSD. Having the SSDoperational when the primary display and/or ventilator is powered downalso has the benefit of allowing an operator to determine the status ofvarious information without the need to power up/boot up the GUIcontroller or other non-essential systems. For example, during theselection of a ventilator system, a ventilator operator may refer toinformation (such as identification information, ventilationconfiguration features, a list of ventilator programs executable by theventilator system, and/or maintenance information) provided by the SSDwithout having to power on the ventilator system or the electric GUI.Having quick and easy access to this information reduces the amount oftime necessary for a ventilator operator to choose a desirable/properventilator.

In an embodiment, the SSD is a display located on the gas deliverysystem. In one embodiment, the SSD is a small, low-power display such asan LCD display to reduce the power demand of the SSD. In one embodiment,the SSD is always powered on when the ventilator is under battery power.In another embodiment, the SSD is always powered on when the ventilatoris receiving external power. In yet another embodiment, when theventilator is running on battery power, the SSD may power off and may beturned on using a separate SSD power switch (different from thatcontrolling the primary display and electronic GUI and/or theventilator). In one embodiment, the SSD or drive circuitry may be ableto determine when the primary display is turned off or removed (ifremovable), during ventilation and may automatically turn on and remainon in such circumstances. In an alternative embodiment, the SSD mayalways be powered on when the ventilation is off but receiving externalpower. Further in another embodiment, the SSD or drive circuitry may beable to determine when the ventilator is turned off and mayautomatically turn the SSD on if the ventilator is receiving externalpower.

In an embodiment, when the SSD is on, the SSD may be programmable by theoperator or manufacturer to meet local requirements or preferences.Likewise, the status data (that is data obtained from systems other thanthe GUI controller) displayed and the format of that display may also beuser selectable.

In order to properly treat a patient, an operator must be familiar withthe configuration of the ventilator system. However, various ventilatorsare configured in various ways, making it difficult for an operator toquickly find and locate components of a ventilation system. Accordingly,in one embodiment, the ventilator system described herein displays atwo-point perspective view representing the physical configuration of aportion of the ventilator system on the SSD or electric GUI. Further,key components and ventilator system status may be displayed on thistwo-point perspective view representing the physical configuration of aportion of the ventilator system in the actual physical location ofthese components on the ventilator system. Accordingly, this displaymethod decreases the amount of time necessary for a ventilator operatorto locate various physical ventilator components on the ventilatorsystem for providing proper patient ventilation.

FIG. 1 illustrates an embodiment of a ventilator system 20 (alsoreferred to as ventilator 20) including a primary display 59, a systemstatus display 51, a controller 50, and a pneumatic system 22 (alsoreferred to as a gas delivery system 22). The ventilator system 20further includes a main housing.

Ventilator 20 is connected to a human patient 24. Pneumatic system 22(also referred to as a gas delivery system 22) delivers breathing gasesto a patient 24 via the ventilation tubing system 26, which couplespatient 24 to the pneumatic system 22 via physical patient interface 28and ventilator circuit 30. The gas delivery system 22 is located in themain housing of ventilator 20. Ventilator circuit 30 could be a two-limbor one-limb circuit 30 for carrying gas mixture to and from the patient24. In a two-limb embodiment as shown, a wye fitting 36 may be providedas shown to couple the patient interface 28 to the inspiratory limb 32and the expiratory limb 34 of the circuit 30.

The present description contemplates that the patient interface 28 maybe invasive or non-invasive, and of any configuration suitable forestablishing a flow of breathing gas from the patient circuit 30 to anairway of the patient 24. Examples of suitable patient interface 28devices include a nasal mask, nasal/oral mask (which is shown in FIG.1), nasal prong, full-face mask, tracheal tube, endotracheal tube, nasalpillow, etc.

Pneumatic system 22 may be configured in a variety of ways. In thepresent example, system 22 includes an expiratory module 40 coupled withan expiratory limb 34 and an inspiratory module 42 coupled with aninspiratory limb 32. The inspiratory limb 32 receives a gas mixture fromone or more gas sources controlled by one or more gas metering devices.The pneumatic system 22 may include a variety of other components,including other sources for pressurized air and/or oxygen, gas meteringdevices, accumulators, mixing modules, valves, sensors, tubing, filters,etc.

Controller 50 is operatively coupled with pneumatic system 22, signalmeasurement and acquisition systems, and an operator interface 52. Theoperator interface 52 may be provided to enable an operator to interactwith the ventilator 20 (e.g., change ventilator settings, selectoperational modes, view monitored parameters, etc.). Controller 50 mayinclude memory 54, one or more processors 56, storage 58, and/or othercomponents of the type commonly found in command and control computingdevices.

The memory 54 is non-transitory computer-readable storage media thatstores software that is executed by the processor 56 and which controlsthe operation of the ventilator 20. In an embodiment, the memory 54comprises one or more solid-state storage devices such as flash memorychips. In an alternative embodiment, the memory 54 may be mass storageconnected to the processor 56 through a mass storage controller (notshown) and a communications bus (not shown). Although the description ofnon-transitory computer-readable media contained herein refers to asolid-state storage, it should be appreciated by those skilled in theart that non-transitory computer-readable storage media can be anyavailable media that can be accessed by the processor 56. Non-transitorycomputer-readable storage media includes volatile and non-volatile,removable and non-removable media implemented in any method ortechnology for storage of information such as computer-readableinstructions, data structures, program modules or other data.Non-transitory computer-readable storage media includes, but is notlimited to, RAM, ROM, EPROM, EEPROM, flash memory, non-volatile memory,or other solid state memory technology, CD-ROM, DVD, or other opticalstorage, magnetic cassettes, magnetic tape, magnetic disk storage orother magnetic storage devices, or any other medium which can be used tostore the desired information and which can be accessed by the processor56.

The controller 50 issues commands to pneumatic system 22 in order tocontrol the gas delivery provided to the patient 24 by the ventilator20. The specific commands may be based on inputs received from patient24, pneumatic system 22 and sensors, operator interface 52 and/or othercomponents of the ventilator 20.

In the depicted example, operator interface 52 includes a primarydisplay 59 that is touch-sensitive, enabling the primary display 59 toserve both as an input user interface and an output device. The primarydisplay 59 is removable from the ventilator system 20. In an alternativeembodiment, the primary display 59 is not removable from ventilatorsystem 20. The primary display 59 can display any type of ventilationinformation, such as sensor readings, parameters, commands, alarms,warnings, and smart prompts (i.e., ventilator determined operatorsuggestions).

The primary display 59 is an electronic Graphical User Interface (GUI)that allows the operator to view patient data in different forms, viewhistorical data, control the operation of the ventilator 20, and tochange the therapy being provided to the patient. In an embodiment,every ventilator operation that can be performed by the ventilator 20can be accessed via the electronic GUI or primary display 59. In anotherembodiment, a portion of the ventilator operations that can be performedby the ventilator 20 can be accessed via the electronic GUI of primarydisplay 59.

In one embodiment, primary display 59 utilizes a separate GUI controller(not shown), which may alternatively be referred to as the primarydisplay controller or graphics subsystem. A separate GUI controller maybe utilized because the computing power necessary to drive primarydisplay 59 is often solely dedicated to running the primary display,interpreting user inputs received through the GUI, and passing thatinformation on to main ventilator controller 50 that controls the actualgas delivery operations of ventilator 20 and any subsystems withinventilator 20.

Primary display 59 also performs the computations and manipulationsnecessary to convert raw data, provided by main ventilator controller 50or discreet ventilator subsystems, into the graphical presentations,such as waveforms, loops, monitored patient data, and/or average valuesfor display on the GUI. This list is not limiting. Any suitable type ofgraphical presentation for a primary display 59 may be utilized. In oneembodiment, the raw data and the generated graphical presentations arestored in memory to be accessed as needed by the GUI controller ofprimary display 59.

In this embodiment, ventilator 20 includes a battery control system (notshown). Medical ventilators may be provided with one or more batteriesto allow ventilator 20 to remain in operation without interruption whilea patient is being transported between locations or during power loss.In this embodiment, the ventilator 20 monitors the charge state andperformance of the battery or batteries and keeps the batteries in acharged state. In this embodiment, the primary display 59 and/or SSD 51is in communication with the battery control system and displays batteryinformation received from the battery control system, such as batteryuse, battery performance, and battery charge levels.

In an alternative embodiment, the primary display includes a primarydisplay battery control system that monitors the charge state andperformance of the battery or batteries in ventilator system 20 and/orin the primary display 59 and keeps the batteries in a charged state. Inthis embodiment, the primary display 59 and/or SSD 51 independentlycommunicates with the primary display battery control system anddisplays battery information received from the battery control system,such as battery use, battery performance, and battery charge levels.

Ventilator 20 further includes system status display (SSD) 51. The SSD51 is a secondary display that provides limited status information tothe operator. IN this embodiment, SSD 51 is not interactive in any way.SSD 51 displays status information in a predetermined or preselectedformat. In alternative embodiments, the SSD 51 provides for limitedinteractions, such as a set of commands provided directly to thecontroller 50.

SSD 51 is completely independent of the GUI controller on the primarydisplay 59. Accordingly, if the primary display 59 with the GUIcontroller fails, is disconnected, is removed from the ventilator 20, ispowered off, or malfunctions, the SSD 51 still provides the operatorwith ventilator and patient information obtained directly from thecontroller 50. SSD 51 allows an operator to determine variousinformation of ventilator system 20 and patient status informationwithout having to power up/boot up, fix, or reattach primary display 59with the GUI controller. In another embodiment, SSD 51 allows anoperator to determine various information of ventilator 20 withouthaving to power up/boot up the entire ventilator system 20.

For example, the SSD 51 of ventilator system 20 may be designed todisplay ventilator information that is helpful to a ventilator operatorprior to use of ventilator 20. In this embodiment, the SSD 51 maydisplay pre-use information, such as identification information,maintenance information, ventilator programs executable by ventilator 20and/or ventilation configuration features. This information provides theventilator operator with necessary information for selecting a properand/or desirable ventilator 20 for each individual patient. Displayingthis pre-use information on the SSD 51 allows information to be viewedquickly without having to power on the ventilator 20 and/or the primarydisplay 59. Further, this SSD 51 groups all of the information necessaryfor selecting a ventilator 20 onto one screen, preventing the operatorfrom having to navigate through several display screens to determine allof the information necessary for selecting a ventilator 20. Accordingly,the display of identification information, maintenance information,ventilator programs executable by ventilator 20 and/or ventilationconfiguration features on the SSD 51 decreases the amount of timenecessary for a ventilator operator to select a proper and/or desirableventilator 20. This time decrease is particularly desirable whenventilating a critical patient or when picking a ventilator 20 in achaotic environment, such as an intensive care unit or in the fieldduring a disaster.

The SSD 51 may display this pre-use information upon command, at alltimes, or in specific power or physical configurations. In oneembodiment, the SSD 51 of ventilator 20 displays identificationinformation, maintenance information, ventilator programs executable byventilator 20 and/or ventilation configuration features continuouslywhen the ventilator 20 is powered off/turned off but receiving powerfrom an external power source. In another embodiment, the SSD 51 ofventilator 20 displays identification information, maintenanceinformation, ventilator programs executable by ventilator 20 and/orventilation configuration features upon user selection when theventilation system is powered off but receiving power from a batterysource. In yet another embodiment, the SSD 51 of ventilator 20 displaysidentification information, maintenance information, ventilator programsexecutable by ventilator 20 and/or ventilation configuration featuresupon user selection when the ventilation system is powered or turned on.

The type of pre-use information that is displayed may be determined byventilator configuration, operator selection, operator input, and/orventilator power or physical configuration. In one embodiment, theoperator may input pre-use information into ventilator 20, such asidentification information and maintenance information. In anotherembodiment, ventilator 20 may determine the pre-use informationcontinuously and/or at upon configuration. For example, ventilator 20may determine if the patient circuit 30 is in a neonate, a pediatric, oran adult configuration based on previous or current settings. In anotherembodiment, the make and model of ventilator 20 may be programmed intoventilator 20 upon configuration.

The identification information is any information that allows anoperator to identify ventilator 20, such as an owner name, an owneraddress, an owner identification number, a model name, a model number, abrand name, a production date, and/or a manufacturer identificationnumber to name only a few. In one embodiment, some of the identificationinformation may be preconfigured into ventilator 20 or inputted by anoperator. For instance, the model name, model number, and productiondate may be preconfigured into ventilator 20. In another example, theoperator may input an owner name, an owner identification number, orother information valuable to the operator for identifying ventilator20.

The maintenance information is any information that allows an operatorto determine the maintenance, service, and/or performance status ofventilator 20. The maintenance information may include serviceinformation or test information.

Service information is any information relating to the service ofventilator 20. The service information may be related to previousservices performed on ventilator 20 or to future services that needs tobe performed on ventilator 20 for proper or desired maintenance ofventilator 20. The service information may include a service type,service date, service time, service reminder, preventative service date,future service information, and/or specific service information forindividual components of ventilator 20, such as a gas source, oximeter,and/or capnograph. The future service information includes informationrelating to any already scheduled/planned future services for ventilator20. The preventative service information includes reminders and/orwarnings that let the operator know when future service should beperformed and/or if a future service is due or past due.

In one embodiment, the SSD 51 displays the most recently performedservice information, such as type of service, date of service, and timeof service. In a further embodiment, the SSD 51 displays the number ofhours ventilator 20 may be utilized to ventilate a patient before thenext service is required. In an additional embodiment, the SSD 51 mayfurther display the last service date for a gas source and the amount oftime until the next service date for the gas source is necessary.

In one embodiment, the test information may be inputted or selected bythe operator and/or service provider. In another embodiment, ventilator20 may determine test information through a program executed bycontroller 50 or a primary display controller. In a further embodiment,the test information may be preconfigured into ventilator 20 andprogrammed to be displayed based on a preconfigured event and/or timeduration.

The test information includes any information relating to any testsperformed on ventilator 20 or any necessary or desirable future testsfor ventilator 20. The test information may include, test type, testdate, test time, test results, future test information, preventativetest information, and/or specific test information for individualcomponents of ventilator 20. In one embodiment, the test informationincludes the absence of a necessary test or test results. In anotherembodiment, the future test information includes information relating toany already scheduled/planned future tests for ventilator 20. Thepreventative test information may include reminders and/or warnings thatlet the operator know when future tests should be performed and/or iffuture tests are due or past due.

In another embodiment, the SSD 51 displays start-up test information. Inyet another embodiment, the SSD 51 displays short self test and/orextended self test information, such as date, time, and results.

In one embodiment, the SSD 51 displays information relating to the mostrecently performed tests, such as type performed, date performed, andtime performed. In a further embodiment, the SSD 51 displays the numberof hours ventilator 20 may be utilized to ventilate a patient before thenext test is required. In an additional embodiment, the SSD 51 mayfurther display the last test date for a gas source and the amount oftime until the next test for the gas source is necessary.

In one embodiment, the test information may be inputted or selected bythe operator and/or service provider. In another embodiment, ventilator20 may determine test information based on a program executed bycontroller 50 or primary display controller. In a further embodiment,the test information may be preconfigured into ventilator 20 andprogrammed to be displayed based on a preconfigured event and/or timeduration.

The ventilator programs executable by ventilator 20 are programs orsoftware that control and/or affect the ventilation of a patient beingventilated by ventilator 20. Different programs may be used to providedifferent types, or ‘modes’, of ventilation, such as volume controlledventilation, pressure controlled ventilation, etc. Examples ofventilation modes used in the art include Continuous Positive AirwayPressure (CPAP), Proportional Assist Ventilation® Plus (PAV+) and VolumeVentilation Plus™ (VV+) to name only a few. These programs may be listedby name, abbreviation, and/or symbol.

Other ventilator programs utilized by the ventilator 20 further requirephysical ventilator configurations for proper use. Accordingly, thelisting of these types of programs also informs the operator that thesephysical configurations are also present on the ventilator 20, such asneomode, autostart, ieSync, non-invasive neonatal CPAP (NIV Neo CPAP),Spontaneous Breath Trial Manager (SBT Manager), and/or Heliox to nameonly a few. For example, Heliox ventilation requires a specific valvefor proper Heliox ventilation and NIV Neo CPAP requires a neonatalnon-invasive patient interface. Accordingly, theses programs whetherlisted by name, abbreviation, and/or symbol represent that ventilatorcontains both the program/software and the physical ventilation systemconfiguration and/or parts for properly executing these ventilatorprograms.

In one embodiment, all of the ventilator programs are displayed by thesystem status display 51. In another embodiment, a portion of theventilator programs are displayed by the system status display 51. Inone embodiment, the ventilator programs displayed by the system statusdisplay 51 are user selected. In another embodiment, the ventilatorprograms displayed by the SSD 51 are preconfigured.

The ventilation configuration features include features that describehow the ventilator 20 is physically configured, such as batteryinstallation status, patient circuit configuration, humidifierconfiguration, compressor installation status, communication systeminstallation status, external flow measurement system installationstatus, nebulizer installation status, and/or gas source installationstatus to name only a few. Battery installation status displayed on thesystem status display 51 informs the operator of what batteries areinstalled on the ventilator 20. In one embodiment, the batteryinstallation status may further inform the operator what the chargelevel is of each installed battery. In another embodiment, the batteryinstallation status may further inform the operator of which battery ischarging or in use. Patient circuit configuration information displayedby the system status display 51 informs the operator if the patientcircuit 30 of ventilator 20 is in a neonate, pediatric, or adultconfiguration. Humidifier configuration information displayed on thesystem status display informs the operator if a humidifier is utilizedby ventilator 20 and if utilized, what kind of humidifier is utilized bythe ventilation system. Compressor installation status informationdisplayed by the SSD 51 informs the operator if a compressor isinstalled on ventilator 20. Gas source installation status informationdisplayed by the system status display 51 informs the operator of whatkinds of gas sources are installed on ventilator 20.

In one embodiment, SSD 51 is located on the housing of ventilator 20. Inan embodiment, SSD 51 displays status information and is always on whenventilator 20 is provided with battery power and/or external power(e.g., when it is plugged into a wall socket). In the embodiment shown,the SSD 51 is a small, low-power display, such as an LCD display. In analternative embodiment, SSD 51 is powered off unless an operator turnsthe SSD 51 on (with a different power switch from that controlling theprimary display 59 and/or ventilator 20) when ventilator 20 is providedwith battery power and/or external power. In another embodiment, SSD 51has drive circuitry to determine when the primary display is turned off,disabled, failing or removed from ventilator 20 (e.g., such as fortransport to conserve battery life) and automatically turns on for aportion of time. In this embodiment, SSD 51 may remain on. In anotherembodiment, SSD 51 remains on until the operator switches SSD 51 off,SSD 51 runs out of power, the primary display 59 is turned on, is fixed,or is reattached, and/or an external power source is utilized. Inanother embodiment, SSD 51 has drive circuitry to determine when the SSDis turned off or turned on.

In one embodiment, SSD 51 is programmable by the operator ormanufacturer to meet local requirements or preferences. Further, statusdata (that is obtained from systems other than the GUI controller of theprimary display 59) is displayed. In another embodiment, the format ofthe data displayed on the SSD 51 is selected by the operator ormanufacturer.

In one embodiment, ventilator 20 may be configured to display atwo-point perspective view representing a physical configuration of aportion of ventilation system 20. The two-point perspective illustrationmay be displayed by SSD 51 and/or primary display 59.
